Three orange lights in the sky over Little River, SC in a triangle formation

I saw 3 circular orange lights, in a triangle formation in Little River, SC, just a few miles outside North Myrtle Beach. This was at 10:35pm 7/18/2012. It was a pretty clear night with only a few wispy clouds moving through the sky. I was parking my car at my condo after work and happened to look up. I heard nothing that would indicate it was an airplane, etc. The lights went away all at once. I don't know how long it had been there before I had looked up. I looked at it for about 2 minutes not believing what I was seeing.
